Re: [riot-devel] Network Stack Task Force
Hello Martin, 2015-02-06 9:02 GMT+01:00 Martin martin.landsm...@haw-hamburg.de: thx again for recording the audio for the introducing presentation. It was a great help to get a more descend look at the information from the slides and the idea for the message based network stack approach. Great! Yesterday we got the foundamental concept how the new network stack will evolve, which modules are covered yet and what parts are open for discussion/definition. As I couldn't attend, I humbly ask how the meeting will proceed today, and if there was discussion/consensus on open topics? Yesterday after the talk we discussed how to solve routing in the network stack. Basically we decided, that for proactive routing the FIB (for a given destination address it gives an PID/interface + next hop address) you proposed is sufficient. For reactive routing we concluded, that it is probably best for the FIB to return for a given destination address the PID of the routing protocol with next hop address == NULL, if a next hop is not available. This way we only need to check in IP if the next hop address is != NULL to lookup the link layer address in the NIB and then send the packet to the given PID. The routing protocol is in case of reactive routing then responsible for the packet and might either send it itself to the link layer or resend it to IP after a next hop was found or drop it if not. We also discussed error management for sending and receiving. The result was, that we introduce a 6th message type for netapi to communicate the status of a packet for a certain layer, and a protocol can register to those via netreg. I'll propose an interface for this at today's meeting. The plan for today is to discuss Header Options, ICMPv6, neighbor discovery and something something I forgot right now ^^ Best, Martine ___ devel mailing list devel@riot-os.org http://lists.riot-os.org/mailman/listinfo/devel

Re: [riot-devel] Call for OTA (Over the Air Update) Task Force
Thanks everyone for the input so far, it looks like there is a decent agreement on some core concepts, and there is a strong interest to contribute them. I would like to propose to continue with a virtual meeting, to: - present a summary(!) of the use cases and requirements posted on the ML - break them down into layers (such as bootloader, flash, etc) - for each of those layers, get a rough idea about what exists already today, or what we can do to help create them. Since this is a fairly industry-heavy crowd, i would suggest having the meeting during central european work hours for 2 hours. http://doodle.com/mtzr2s9fbdx72sun I will read all the comments on this doodle and try to adjust accordingly, so please also post your preferred time of the day. best, Arvid ___ devel mailing list devel@riot-os.org http://lists.riot-os.org/mailman/listinfo/devel

Three packets every second shouldn't be a problem. Have you checked if

indicator if
it's a general problem in - let's say the network stack - or if it's
